What are Mineral Fillers?
Mineral fillers are finely ground natural minerals added to various materials to improve properties, reduce costs, and enhance performance. The most common mineral fillers include:
- Calcite Powder - Pure calcium carbonate (CaCO₃) with exceptional brightness
- Dolomite Powder - Calcium magnesium carbonate (CaMg(CO₃)₂) with superior strength
- Ground Calcium Carbonate (GCC) - Versatile filler for multiple applications
- Coated Minerals - Surface-treated fillers for enhanced polymer compatibility
Types of Mineral Fillers
1. Calcite Powder Fillers
Calcite powder is one of the most widely used mineral fillers due to its high brightness (95-98%), low oil absorption, and excellent dispersibility. It's ideal for:
- Paint and coating applications
- Plastic manufacturing
- Paper production
- Rubber compounding

2. Dolomite Powder Fillers
Dolomite powder offers superior mechanical strength and fire resistance, making it an excellent mineral filler for:
- Construction materials
- Ceramics and glass manufacturing
- Plastic reinforcement
- Cost-effective filler applications

Frequently Asked Questions — Mineral Fillers
Mineral fillers are finely ground inorganic minerals added to industrial products to improve properties, reduce costs, or add functionality. Common mineral fillers include
calcite powder,
dolomite powder,
limestone powder, and
ground calcium carbonate (GCC). They are used in paints, plastics, rubber, paper, construction, and adhesives.
Mineral fillers are used across many industries: paints & coatings (extender pigments for opacity and cost reduction), plastics (PVC, PP, HDPE films and profiles), rubber (tires and industrial rubber goods), paper (filler and coating pigment), construction (cement, concrete, tile adhesives), adhesives & sealants, and agriculture (soil amendment and fertiliser carrier).
Calcite powder (CaCO₃) offers higher brightness (95–98%) and is preferred for paints and plastics where whiteness is important.
Dolomite powder (CaMg(CO₃)₂) contains magnesium carbonate, giving it higher hardness and heat resistance — making it better for glass, ceramics, and construction. See our full comparison:
Calcite vs Dolomite Powder.
Shikhar Microns supplies mineral fillers in 100 to 1500 mesh. Coarser grades (100–300 mesh) suit construction and agriculture; medium grades (400–600 mesh) are standard for paints and plastics; fine grades (800–1500 mesh) are used for high-performance coatings, paper, and specialty plastics. Custom particle sizes are available on request.
Key selection factors include: particle size (mesh/micron), purity (CaCO₃ or CaMg(CO₃)₂ %), brightness (GE/ISO), oil absorption, chemical composition, and coating requirement (coated vs uncoated). Contact our technical team — we help match the right filler grade to your process and end-product specifications.
